This invention is for improvements in or connected with laundry presses and has `for one of its objects to improve the efficiency and simplify the construction of the pressure bucks. The invention is concernedwith presses of the type in which the pressure bucks are heated by steam or other fluid. k

According to the primary feature of the present invention, thereA is provided a pressure buck for a laundry press, comprising a wall one face `of which is the pressure-applyingface and the opposite face of which has a multi-channel-shaped member attached to it in such manner as, with the said wall, to form conduits for the passager of a fluid for heating thewall. Conveniently the said channel-shaped member is of corrugated sheet formation and the valleys of the corrugations are attached to said wall in such manner that between adjacent valleys there is a heating fluid conduit formed by the corrugation and the wall. It is preferred to have Lthe endsof the conduits closed, and to have portions of the lengths of said valley'spaced awayy from the wall I to afford restricted communication between adjacent conduits. Thus the heating fluid can pass not only along the conduits but also between adjacent conduits. The valleys may be dimpled at intervals along their length and welded to the wall at the situations of the dimples, this ar rangement ensuring that the Valleys are adequately secured to the wal1 while affording communication between adjacent conduits.

For a more complete understanding of the in-v vention there will now be described, yby way of example only and with reference to the accompanying drawings, `one constructional form of pressure buck according to theinvention. It is to be understood, however, that the invention is not restricted to the precise constructional details set forth.

In these drawings:

Figure 1 is a side elevation of a portion of a laundry press which includes a pressure buck according to the present invention;

Figure 2 is aY sectional elevation on the line 2-2 of Figure 3 of the pressure buck shownY in Figure 1 but on a scale larger than that of Figure 1;

Figure 3 is a plan of the pressure buck shown in Figure 1 but on a scale larger than that of Figure` 1;

Figure 4 is a detail sectional View on the line 4-4 of Figure 3 but on a scale larger than that of Figure 3, and

5-5 of Figure 3, but on the same scale as 'thatIW of Figure 4.

Like reference numerals indicate like parts Theupper pressure buck comprises a wall I3' which, as illustrated, is of cylindrical formation but may be of any other preferred shape. The' lower face of this wall I3, as seen in Figure 2, is the pressure-applying face. The upper. face of the wall I3 has attached to it a channelshaped member I4 of corrugated sheet formation which may either be made as a single piece or as a number of separately formed units welded or otherwise secured together. The lateral extremities of the. member III` are continuously welded to the wall I3 at I5 and I6, making tight joints, andthe valleys II of the member I4 are dimpled at I8 at intervals along their length as clearly seen in Figures 4 and 5. The dimples I8 are perforated so that the valleys I'I may be welded as at I9 through the perforations to the wall I3. Thus between the dimples in any one valley lengths of the latter are spaced away from the wall I3 as shown at 20 in Figure 4, to afford restricted communication between the spaces at each side of the valley. I Y

'I'he corrugations in the member I4 form, with the wall I3, conduits 2| and the ends of these conduits are closed by plates 22 and 23 which are continuously welded at 24 to the membery I4 and at 25 to the wall I3, making tight joints.

From the foregoing description it will'be seen that the conduits 2| extend from end to end of the wall I3 and are in communication with each other through the spaces 20. To provide for the circulation of steam or other heating medium through the conduits 2|, widely spaced branches 26 and 21 are tted, the former serving for intake and the latter for exhaust. The pipes connected to the branches 26 and 21 will be flexible or jointed to partake of the movement of the buck with its arm I2. On the side of the buck opposite to that at which the branches 26 and 21 are located, is a valve-controlled vent 28 which may be used to permit the exhaust of air, say when starting up the heating of the buck. Any

Figure 5 is a detail sectional view on the line 55 liquid forming in or reaching the conduits 2l will be able to pass away through the branch 2'I when the buck arm I2 swings away into its inoperative position.

The corrugated member I 4 being attached to many points to the Wall I3 will stiffen the latter in addition to enabling the Wall to be heated. Studs 29 are welded or otherwise attached to the member I4 and the end plates 22 and 23 for use in securing a covering sheet to the wall I3.

As illustrated in Figure l, the upper buck is secured to the arm I2 by a ball-and-socket connection. The socket 30 is welded between two bridge plates 3I and 32 which extend transversely across the corrugated member I4 and are welded at intervals at 33 to the latter. As will be seen from Figure 2, the bridge plates 3| and 32 t the external contour of the corrugations and reach into the valleys thereof, thus assisting to prevent distortion and ensuring adequate interconnection of the parts. The slotted plate 34 reaching out from the socket 30 co-operates with a pin 35 depending from the arm I2 to prevent undue swinging of the buck about the aforesaid ball-and-socket connection.

It is to be understood that the invention is not restricted to the precise constructional details set forth. For instance, the invention is not limited to being applied to movable pressure bucks. Nor is it essential to weld the various parts of the buck together as other securing means and jointing means may be employed. Moreover instead of dimpling the valleys equivalent spacing Washers may be provided which may be welded, riveted or otherwise held in place.

We claim:
